Check the listing for details. Microsoft Wireless Presenter Point Pen Slide PowerPoint Clicker Remote NO DONGLE. Color: Black, Condition: Used, Made in China. Listed at 9.98 USD. Actual Photos Shown: This little remote is in great cosmetic condition. The method used for testing was using the phone camera in a dark room and pushing a button on the remote while focusing the camera on the infrared lightbulb. In the last photo it is demonstrated that the infrared bulb which transmits the signal is working fine. That being said I am fairly confident computers don’t regularly include infrared receivers so in order to make this work I believe there is a special dongle that must be purchased that may have originally come with it. In order for it to work with the computer I’m fairly confident that this infrared dongle or receiver, is required. All Sales Are Final ~Ships Same Day~
